  You can use the same money to: a) put solar panels over the truck b) put solar panels in a fixed spot, where it's easier to use big panels, maintain them, avoid nasty vibrations, and transport the energy to a charger. In b) you get more energy, even after transferring it to the truck. So you can use the extra energy to power other truck or a home or something, and then avoid burning fossil fuel and then saving the panel. The option b) is more environmental friendly.
